+# Binary HTTP Messages
+
+This is a rust implementation of [Binary HTTP
+Messages](https://www.rfc-editor.org/rfc/rfc9292.html).
+
+## Using
+
+The API documentation is currently sparse, but the API is fairly small and
+descriptive.
+
+The `bhttp` crate has the following features:
+
+- `read-bhttp` enables parsing of binary HTTP messages. This is enabled by
+ default.
+
+- `write-bhttp` enables writing of binary HTTP messages. This is enabled by
+ default.
+
+- `read-http` enables a simple HTTP/1.1 message parser. This parser is fairly
+ basic and is not recommended for production use. Getting an HTTP/1.1 parser
+ right is a massive enterprise; this one only does the basics. This is
+ disabled by default.
+
+- `write-http` enables writing of HTTP/1.1 messages. This is disabled by
+ default.
